However, the present application can be realized in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terminology used in the description of the present application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the present application.

[0035] Embodiment:

[0036] Referring to Figures 1-6 The present embodiment provides a dust suppression and environment-friendly stacker for port, comprising:

[0037] The belt conveyor 3 is provided with a material guide groove 6 at the material conveying section of the conveying belt 34 and is provided with a discharge hopper 35 at the discharge end, the discharge end is wrapped by the discharge hopper 35, and the end of the material guide groove 6 close to the discharge point is connected with the discharge hopper 35; the material guide groove 6, the material conveying section of the conveying belt 34 and the discharge hopper 35 form a sealed material conveying channel; further, the material conveying section in the present embodiment refers to the section of the conveying belt between the receiving point and the discharge point, and the discharge end and the receiving end refer to the two ends of the belt conveyor; of course, in specific design, the discharge point and the discharge end can be the same position, the receiving point and the receiving end can be the same position, or the discharge point and the discharge end can not be the same position, and the receiving point and the receiving end can not be the same position.

[0038] The dust suppression mechanism 9 includes a first nozzle 95, a second nozzle 96, and a negative pressure dust removal device; the material guide trough 6 is provided with a plurality of first nozzles 95 at intervals along the material conveying direction for spraying water mist into the material conveying channel at one end near the receiving point, and a negative pressure dust removal device is provided behind the first nozzle 95 farthest from the receiving point, the dust removal port of the negative pressure dust removal device is connected to the material conveying channel; the discharge port of the discharge funnel 35 is provided with a plurality of second nozzles 96 for spraying water mist around its discharge port.

[0039] In this embodiment, the stacker forms a material conveying channel through the guide trough 6, the material conveying section, and the unloading hopper, which can effectively prevent dust from overflowing during material transportation. The negative pressure generated by the negative pressure dust removal device can guide the dust generated during material receiving forward (i.e., along the material conveying direction). When the dust flows forward, it is moistened by the water mist sprayed by the first nozzle 95 and settles to the material surface, thereby achieving the purpose of dust reduction. At the same time, the negative pressure dust removal device can also adsorb some of the dust. Furthermore, the multiple second nozzles 96 arranged around the unloading port can spray water mist to form a mist curtain during unloading, effectively suppressing the dust generated during unloading.

[0040] See Figure 1 and Figure 2 The guide trough 6 has multiple partition curtains 61 spaced apart along the material conveying direction at one end near the unloading point. The partition curtains 61 are located in the upper part of the internal space of the guide trough 6 (i.e., the top of the material conveying channel). By spacedly setting the partition curtains 61, the path of dust moving forward above the conveyor belt 34 can be blocked, and multiple relatively enclosed spaces can be formed above the conveyor belt to promote the settling of wetted dust, which can effectively solve the dust problem near the unloading point and above the conveyor belt of the belt conveyor.

[0041] See Figure 5 In this embodiment, the lower part of the material guide trough 6 is provided with a sealing element 62. The sealing element 62 is in soft contact with the material conveying section of the conveyor belt 34, thereby achieving a sealing effect between the material guide trough 6 and the conveyor belt 34, effectively preventing dust from overflowing. Specifically, the sealing element 62 is preferably made of rubber.

[0042] See Figure 1 and Figure 2 The output port of the negative pressure dust removal device is connected to the water tank 92 through a pipe, and the water tank 92 achieves the effect of purifying dust. Preferably, the negative pressure dust removal device is an exhaust fan. The negative pressure generated by the exhaust fan allows the dust to move along the material conveying direction, and at the same time, it can also adsorb some of the dust and send it to the water tank 92 for treatment, thereby increasing the dust handling capacity of the stacker.

[0043] Preferably, in this embodiment, the guide trough 6 extends to the receiving end of the belt conveyor 3. The end face of the guide trough 6 at the receiving end is sealed. The guide trough 6 has a receiving port at the receiving point. That is, the entire conveyor belt on the upper surface of the belt conveyor 3 forms a material conveying channel with the guide trough 6. Only the receiving port is left at the unloading point so that the material can enter the material conveying channel. This arrangement can effectively prevent dust from overflowing.

[0044] See Figure 1 , Figure 2 and Figure 5 The material guide trough 6 has a main water supply pipe 93 on its outer side near the receiving point. The length of the main water supply pipe 93 is parallel to the material conveying direction. Multiple branch pipes 94 are spaced apart on the main water supply pipe 93, extending into the interior of the material guide trough 6, and each branch pipe has a first nozzle 95 at its end. Furthermore, both the main water supply pipe 93 and each branch pipe 94 are equipped with a solenoid valve to control the water supply and the on / off state of each first nozzle 95. Additionally, the second nozzles 96 are also supplied with water through pipelines, and each second nozzle 96 is controlled by a solenoid valve. In this embodiment, both the first and second nozzles are micron-level water mist nozzles.

[0045] Preferably, the feed trough is based on existing technology and is typically assembled from 2m or 3m sections.

[0046] See Figures 1-3 The receiving end of the belt conveyor 3 is connected to the rotating support 1. A bracket 4 is provided between the receiving end and the unloading end of the belt conveyor 3. The belt conveyor 3 is mounted on the bracket 4. A traveling mechanism 8 is provided at the lower end of the bracket 4 and is mounted on the arc-shaped track 2. The rotating support 1 is capable of rotational movement and generally includes a fixed part and a rotating part. The fixed part is fixedly installed, and the receiving end of the belt conveyor is connected to the rotating part. When the traveling mechanism 8 moves the belt conveyor 3 on the arc-shaped track 2, the rotating support provides a degree of freedom, allowing the belt conveyor 3 to rotate around its receiving end. Preferably, the receiving end of the belt conveyor and the rotating part of the rotating support can be fixedly connected or hinged. Preferably, the traveling mechanism 8 is existing technology and will not be described in detail in this embodiment. Both ends of the arc-shaped track 2 are provided with stop bars 21 to limit the range of motion of the traveling mechanism and prevent the traveling mechanism from derailing.

[0047] Preferably, in this embodiment, the belt conveyor 3 is suspended from the support 4 by steel wire ropes 5, and the number of steel wire ropes can be set according to the situation. Of course, in some embodiments, the support 4 can also be set below the belt conveyor 3 to support the belt conveyor 3. Regardless of the method, the belt conveyor 3 can rotate around its receiving end.

[0048] See Figures 1-4 In this embodiment, the belt conveyor 3 includes a frame body 31, a drive roller 32, a conveyor belt 34, a tensioning device 36, and N redirecting rollers 33, where N is a natural number greater than or equal to 3.

[0049] The frame body 31 is suspended on the support 4 by steel wire rope and its receiving end is connected to the rotating support 1. The frame body 31 is provided with a redirecting roller 33 at both the receiving end and the unloading end. The support 4 is provided with a tensioning device 36, a drive roller 32 and at least one redirecting roller 33. At least one of the redirecting rollers 33 on the support 4 is installed on the support 4 by the tensioning device 36.

[0050] The conveyor belt 34 is annular and is sequentially wound around the drive roller 32 and N redirecting rollers 33. The drive roller 32 is connected to the output end of the drive device 39, thereby driving the conveyor belt 34 to work. Further, the drive device 39 is mounted on the bracket 4, and the drive device 39 is preferably a combination of a motor and a reducer. The tensioning device 36 is used to tension the conveyor belt 34, which can effectively solve the problem of the conveyor belt easily becoming loose and slipping. In this embodiment, the tensioning device 36 is a counterweight type tensioning device, which is existing technology and therefore will not be described in detail in this embodiment; of course, other structural forms of tensioning devices may also be used in some embodiments.

[0051] See Figure 1 , Figure 2 and Figure 6 The port stacker also includes a cleaning mechanism 7, which includes a receiving hopper 71 and a chute 72 connecting to the receiving hopper 71. A drive roller 32 is located inside the receiving hopper 71. The receiving hopper 71 is equipped with a scraper 73 and a roller brush 74. Both the scraper 73 and the roller brush 74 are used to clean residual material from the conveyor belt's working surface. The roller brush 74 is driven by a motor to rotate in the opposite direction to the drive roller. The roller brush has bristles circumferentially arranged, and the bristles contact the conveyor belt's working surface to clean the residual material. Preferably, the chute 72 and the receiving hopper 71 are connected by a flange.

[0052] See Figure 1 , Figure 2 and Figure 3The frame body 31 is provided with a ladder 37 and a walkway 38, and guardrails are provided on both sides of the walkway 38. Preferably, in this embodiment, walkways 38 are provided on both sides of the conveyor belt to facilitate the inspection and maintenance of the belt conveyor. The ladder 37 is located close to the receiving end, and the height of the receiving end from the bottom surface is small, so the length of the ladder can be designed to be shorter, and it will be safer for personnel to pass through.

[0053] It should be noted that the structure for preventing dust spillage in this embodiment can also be used in other types of belt conveyors. For example, a belt conveyor includes a body, a conveyor belt, and two conveyor rollers. Conveyor rollers are respectively installed at both ends of the body, and the conveyor belt is fitted onto the two conveyor rollers. One of the conveyor rollers is connected to the output end of a motor. This structure can also realize the conveying and stacking of materials. Furthermore, the belt conveyor in this structure may be equipped with a support 4, a traveling mechanism, and an arc track 2 at the bottom to enable the belt conveyor in this structure to rotate. Even further, the belt conveyor in this structure may also be equipped with a tensioning device.

[0054] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
